PRODUCTION
As operator for the Alvheim, Bøyla, Volund and Vilje fields, Det norske has become a major producer
of oil and gas. The Alvheim FPSO (floating production, storage and offloading unit) is a flagship, both
for the company and for the area. From 1.63 million barrels of oil equivalent produced in 2013, Det
norske’s production had an enormous increase to 24.3 million barrels of oil equivalent in 2014.
This increase means that Det norske is now one of the
biggest independent listed oil companies in Europe,
measured by production.
ted from the field to market by shuttle tanker, and gas is
exported through the pipeline system Scottish Area Gas
Evacuation (SAGE) to St Fergus in Scotland.
The Alvheim area
The core of the company’s production is from the Alvheim
area in the northern part of the North Sea. The Alvheim
Asset consists of the producing fields Alvheim, Volund
and Vilje. On 19 January 2015, production started from
the Bøyla field. These four fields have been developed
as subsea fields tied back to the Alvheim FPSO.
Unique production
Production on the Alvheim field started in June 2008,
from the Kneler and Boa structures. In July the same year,
production started from the Vilje field, and in September
2009 from the Volund field. The Alvheim FPSO operates
with world-class regularity, and debottlenecking has
increased the production vessel’s production capacity
from the original 120 000 barrels of oil per day to more
than 150 000 barrels per day. At the end of 2014, 280
million gross barrels of oil (309 million gross barrels of
oil equivalent) had been produced over the Alvheim
facilities. In 2014, Alvheim contributed to 97 per cent
of the company’s production.
At the turn of the year, the Alvheim Asset consisted of
seven separate clusters of wells connected to the FPSO
by pipelines. The area then had a total of 23 production
wells and two water injection wells and two produced
water disposal wells. The oil from Alvheim is transpor-

In February 2015, Det norske was awarded the “Field
Operator of the Year” award for the work done to operate and develop the Greater Alvheim Area. The award,
Gullkronen 2015, organized by Rystad Energy, is an
acknowledgement by the jury that “Det norske has delivered on many levels simultaneously, such as reserve
replacement, regularity, HSE and the establishment of
a new hub in the area”.

Further development of the area
At the end of 2014, Det norske and its partners sanctioned the development of the Viper and Kobra structures,
which are located within the Alvheim licence. The two
separate discoveries are geographically located close to
Volund. They are both part of licence 203. Combined,
the two reservoirs contain recoverable reserves of
approximately 9 million barrels of oil equivalent. Viper
and Kobra will be developed with subsea facilities tied
back to the existing Volund subsea facilities, and with
processing on the Alvheim FPSO. Drilling is scheduled
5 000 000
to start in spring 2016, and production start-up is provisionally forecast to 4Q 2016.
Currently Det norske is executing a programme of
Alvheim infill wells that will add three new producers
during the course of 2015 and early 2016.
Production from several fields
Det norske is also operator for the Jette field. This is the
company’s first operated development project. It started
production in 2013.
In all, the company had ownership interests in seven
producing fields at the turn of the year. The company is
operator for Alvheim (65 per cent interest), Vilje (46.9
per cent), Volund (65 per cent) and Jette (70 per cent).
The company is a partner in Atla (10 per cent), Jotun
(7 per cent) and Varg (5 per cent).

Alvheim
The Alvheim field consists of five discoveries, three of which have started production:
Kneler, Boa and Kameleon. It has been decided to develop the remaining Viper and Kobra
discoveries, and production is expected to start in 2016. In all, the expected recoverable
reserves from the field (net for Det norske) are approx. 90 million barrels of oil equivalent.

Vilje
The Vilje field is located 20 kilometres east of Alvheim. The
field produces from three subsea wells that are connected to
the Alvheim FPSO. Vilje is estimated to contain recoverable
reserves of around 11 million barrels of oil equivalent net
for Det norske.
The Alvheim field has been developed in several phases. In the first phase, the field was
developed with ten production wells and two water injection wells. Today, the Alvheim
field consists of 16 production wells and two water injection wells.
